Outline
The shear-tensile properties of bonded joint, self-piercing riveted joint, bolted joint, self-piercing riveted-bonded joint, bolted-bonded joint of HC420/780DP steel and AA6063 extruded aluminum alloy are studied by shear tensile experiments. The results show that self-piercing riveting and bolting can damage the integrity of the plate, and stress concentration occurs in the contact position between the rivets or bolts with the plate during shear tensile process, leading to crack initiation and propagation, and eventually rivet pulling or tearing of AA6063 extrusion aluminum alloy. The structural adhesive increases the stress area of the steel/aluminum joint, and the AA6063 extrusion aluminum alloy with lower strength is broken during shear tensile process. The maximum shear load of bonded joint, self-piercing riveted-bonded joint, bolted-bonded joint are basically the same, but the energy absorption value of self-piercing riveted-bonded joint and bolted-bonded joint increases by 11.8% and 8% respectively compared to adhesive joint. When the steel/aluminum joint is in service under shear tensile load only, it may be considered to use structural adhesive alone for connection without the additional use of self-piercing rivet or bolt.
